Problems solved by technology

[0006] 1. Too many parts need to be removed, resulting in low work efficiency for replacing the milling drum
[0007] 2. During the replacement process, the pulley (driven pulley) was disassembled, so after replacing the milling drum and reinstalling the pulley, the flatness of the three pulleys (drive pulley, tension pulley and driven pulley) must be checked
If the calibration is not performed according to the regulations, the planes of the three pulleys are out of tolerance, which will cause abnormal wear of the transmission belt during operation and seriously affect the service life of the transmission belt
[0008] 3. When the coolant in the milling drum is replaced, it needs to be drained and filled, there is a risk of leakage, and a special container is required for storage during the draining process

Abstract

The invention relates to a milling drum quick-changing structure, a milling machine and a using method of the milling drum quick-changing structure, and belongs to the field of pavement maintenance operation construction equipment. The milling drum quick-change structure comprises a box body, a speed reducer, a milling drum and an internal support body, the milling drum is arranged in the box body through an internal support body; the internal supporting body comprises a supporting cylinder, a flange plate and a shaft end assembly. One end of the supporting cylinder is a closed end, and the closed end is connected with the flange plate; the other end of the supporting cylinder is an open end, and the open end is connected with the moving end of the speed reducer to form a closed inner cylinder cavity. The shaft end assembly is connected with the milling drum and the flange plate through the connecting seat; the whole process of replacing the milling drum is simple and efficient, and the labor intensity is greatly reduced.

Description

technical field [0001] The invention relates to a milling drum quick-change structure, a milling machine and a method for using the milling drum quick-change structure, belonging to the field of road surface maintenance construction equipment. Background technique [0002] Milling machine is a special mechanical equipment for highway and urban road maintenance. It is mainly used for excavation and renovation of highways, urban roads, airports, freight yards, parking lots, etc. It can efficiently remove damaged road surfaces and waste road surfaces, and excavate Potholes and trenches in road surfaces. [0003] The situation that the milling machine needs to replace the milling drum mainly occurs in the following two aspects: firstly, during the construction process, the milling drum of different specifications will be replaced according to the different working conditions; secondly, during the use of the milling drum, the milling drum The tool seat on the outer cylinder surf...
